corporation of New Jersey Application September 12, 1939, Serial No. 294,555 1 Claim. (01. 220-43) The present invention relates to containers such as hinge cover tablet boxes or the like and has particular reference to a hinge cover having a raised cam edge which facilitates opening of the which at its outer edges merges into a continuous surrounding and depending flange which extends down adjacent to and on the outside of the body upright wall, when the cover is in place box. 5 on the body member. The cover flange includes An object of the invention is the provision in a front wall section 26, a rear hinge wall section a tablet box and the like of a hinge cover where- 21, and a'pair of connecting side wall sections 28. in the edge of the cover adjacent its hinged edge The top wall section 25 uniformly slopes or is shaped in a raised curved cam section which curves downwardly toward the flange along three permits the easy snapping open of thecover when edges thereof, i. e., the front and two side edges. a slight pressure is applied to the hinge edge of Along the rear edge of the cover the top wall the box. section extends straight out thus producing in ef- Numerous other objects and advantages of the fect a raised rear edge indicated at 29.

Rocking of the semi-flattened, dome-shaped top wall section 25 cover on the box raises its front edge away from the body and disengages the locking nodes 2|, 34, thus bringing the cover into a released and partially opened position as shown in Fig. 4.

Complete opening of the cover may nowbe effected by merely grasping the released front edge thereof and moving it upwardly.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope or the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

A hinge cover tablet box and the like, comprising a rectangular body member having upstanding front, rear and side walls with their top edges substantially in a single plane, a rectangular cover member having depending walls telescoping over said body walls and connected by a top wall, said cover top wall at its junction with the depending cover side wall being bent downwardly towards the top edge of the body side wall from a point adjacent the rear corner of the box cover towards the longitudinal center of the box to provide a gradually curved fulcrum shoulder which merges into a straight line of contact between cover top wall and top edge of the body side wall when the box is closed, and a floating hinge connection between the rear walls of said members permitting vertical movement between said hingedly connected members, whereby a pinching pressure applied to either rear corner of the members releases said straight line contact and rocks the cover member along said gradually curved shoulder upon the top edge of the body side wall to initially separate the respective front walls of said members and raise said cover into open posltion.
